ConditionalCompilationBlock

A dot-delimited (.) path describing the enclosing scope of the conditional compilation block declaration, or nil if the conditional compilation block isn’t nested (that is, declared at the top-level scope of a module).

For example, the following conditional compilation block declaration has the context "A.B":

enum A {
   enum B {
       #if true
           enum C {}
       #endif
   }
}

The conditional compilation block branches.

For example, the following compilation block declaration has two branches:

#if true
enum A {}
#else
enum B {}
#endif

The first branch has the keyword #if and condition "true". The second branch has the keyword #else and no condition.

A conditional compilation block branch.
